The Zhu Rong Rover traveled a total of1784m, and the Zhu Rong Rover sent back a selfie from the surface of Mars. Comparing the photos taken just after landing, we can see that a thin layer of dust has accumulated on the surface of the rover. Zhu Rong lunar rover has traveled1784m.

According to the data of the National Astronomical Observatory and the National Space Administration, the Zhu Rong rover has traveled 1784 meters. A few days ago, the "Tianwen No.1" orbiter once again passed over the patrol area of the rover, and took a 0.5-meter resolution image of the patrol area of the "Zhu Rong", in which the driving route of the "Zhu Rong" rover was clearly identifiable.

As of March 24th, 2022, Zhu Rong has been working on the surface of Mars for 306 Mars days, with a cumulative driving distance of1784m. Tian Wen 1 orbiter has been in orbit for 609 days, 277 million kilometers away from the Earth. At present, the two rovers are operating normally.

At present, the northern hemisphere of Mars has begun to enter autumn. According to the analysis of previous detection data, autumn is the season with frequent sandstorm weather on Mars, and no obvious sandstorm weather has been observed in Zhu Rong patrol area.

Officials also pointed out that from the selfies sent back, it can be found that a thin layer of dust has accumulated on the surface of the "Zhu Rong" rover compared with the photos taken just after landing.

At the same time, from the telemetry information of the rover, the power generation efficiency of the solar wing is affected to some extent, but the energy is still sufficient.

It is worth mentioning that, in order to cope with the dust cover, the solar wing of China's "Zhu Rong" rover was specially designed at the time of development, and various measures can be taken to deal with the reduction of power generation efficiency caused by dust, but it is not needed at present, and the current energy state is enough to support the rover to continue driving and explore.

▲ (a) Photographed on May, 20265438 19 (the fifth Mars Day after landing), the surface of the rover was not covered with dust.

As can be seen from the figure below, local sandstorms occurred in some parts of Mars in February this year, and the typical features were covered by a lot of dust, which was difficult to distinguish.

It is reported that the scientific objectives of China's "Tianwen-1" mission are to study the features of the landform and geological structure of Mars, the characteristics of the surface soil of Mars and the distribution of water and ice, the material composition of the surface of Mars, the features of the atmospheric ionosphere and surface climate environment of Mars, and the physical field and internal structure of Mars.

Since the Mars probe was launched on July 23, 2020, during the ground fire transfer flight and the orbit around the fire, seven scientific loads, including a medium-resolution camera, a high-resolution camera, a mineral spectrum analyzer and a magnetometer, have been turned on one after another to detect and obtain scientific data.

Photographed in the image center (37.8 east longitude, 72.9 north latitude) on February 10, 2022, there was a local sandstorm, and the ground objects were difficult to distinguish.

During the fire surface work, the staff will carry out environmental perception, fire surface movement and scientific detection on the patrol area as planned, and carry out fine detection on the patrol area through six loads including terrain camera, multi-spectral camera, subsurface detection radar and surface composition detector. At the same time, the circulator will run in the relay orbit, providing stable relay communication for the patrol detection of the rover, and taking into account the surrounding detection.

Officials also said that the "Tianwen-1" orbiter continued to carry out global remote sensing exploration of Mars, focusing on typical landforms and geological units such as craters, volcanoes, canyons and dry river beds, and obtaining its high-resolution images.

It is worth mentioning that on March 7 this year, when imaging the Jezero crater, it also photographed the American rover "Tenacity", which is currently located about 200 meters southeast of its landing site.

Zhu Rong's rover has accumulated1784m22021may 15 Zhu Rong, the first Mars probe in China, successfully landed on Mars. It carries six kinds of scientific detection instruments, such as spectral camera, meteorological measuring instrument, surface composition detector, radar and magnetic field detector, which can detect the environment and substances of Mars.

As of March 24th, 2022, Zhu Rong has worked on the surface of Mars for 306 Mars days, with a cumulative driving distance of1784m.

According to the WeChat official account of China's lunar exploration project, the "Zhu Rong" rover sent back a selfie from the surface of Mars. Comparing the photos taken just after landing, we can see that a thin layer of dust has accumulated on the surface of the rover.

It should be noted that the images obtained by the middle resolution camera of "Tianwen No.1" ringer monitored the sandstorm weather on Mars, and it was found that obvious sandstorm activities began to appear in the area north of 60 north latitude of Mars at the end of 5438+ 10 this year.

Sandstorms on Mars will directly affect the energy acquisition of the rover. According to the telemetry information of the rover, the engineering team judged that the power generation efficiency of the solar wing of Zhu Rong Rover was affected to some extent, but the energy was still sufficient.

It is understood that in order to cope with dust coverage, the solar wing of the rover has been specially designed, and various measures can be taken to deal with the problem of power generation efficiency reduction caused by dust. Not at present, the current energy state is enough to support the rover to continue driving and carry out detection.

Zhu Rong rover has traveled a total of 65,438+0,784 cubic meters. The reporter learned today from the Lunar Exploration and Aerospace Engineering Center of the National Space Administration that a few days ago, the "Tianwen-1" orbiter once again passed over the patrol area of the rover and photographed the 0.5-meter resolution image of the patrol area of the "Zhu Rong". In the picture, the driving route of the "Zhu Rong" rover is clearly discernible.

As of March 24th, 2022, Zhu Rong has been working on the surface of Mars for 306 Mars days, with a cumulative driving distance of1784m. Tian Wen 1 orbiter has been in orbit for 609 days, 277 million kilometers away from the Earth. At present, the two rovers are operating normally.

The "Zhu Rong" rover also sent back a selfie from the surface of Mars. Comparing the photos taken just after landing, we can see that a thin layer of dust has accumulated on the surface of the rover. At the same time, from the telemetry information of the rover, the power generation efficiency of the solar wing is affected to some extent, but the energy is still sufficient.

Experts from the Lunar Exploration and Aerospace Engineering Center of the National Space Administration said that in order to cope with the dust cover, the solar wing of the rover has been specially designed, and various measures can be taken to deal with the problem of power generation efficiency reduction caused by dust. Not at present, the current energy state is enough to support the rover to continue driving and carry out detection.

Mars sandstorm will directly affect the energy acquisition of the rover, which has always been concerned. The engineering team continuously monitored the sandstorm weather on Mars through the images obtained by the middle resolution camera of "Tianwen No.1", and found that from the end of May 38 this year+10, obvious sandstorm activities began to appear in the area north of 60 north latitude of Mars.

Experts said that at present, the northern hemisphere of Mars has begun to enter autumn. According to the analysis of previous detection data, autumn is the season with frequent dust weather on Mars, but no obvious dust weather has been observed in Zhurong patrol area.

The "Tianwen-1" orbiter continues to carry out global remote sensing exploration of Mars, focusing on typical landforms and geological units such as craters, volcanoes, canyons and dry river beds, and obtaining its high-resolution images. On March 7 this year, the American rover "Perseverance" was photographed while imaging the Gezero crater, and it is currently located about 200 meters southeast of its landing site.
